 SPS question/problem
Hello everyone:
I have a acropora that has been doing great. Great color and everything. The past 3 days I have noticed the very tips of the branches turn a dark purple and the polyps on the tops have turned wgite. Well this progressed for a couple days with only 2 of the polyps with the problem. I noticed yesterday that the polyps with the issue started gooping out white stuff. Tonitht when I looked there was about 4 with the same issues and the first two actually had white stringy goo trailing in the current about 2 inches. It looked like snot for lack of a better description. I pouched the polyp and the stuff came off and the purple tips of the coral felt soft like they crumbled a little tiny bit when I touched them. A checked all my other water properties and everything checks out but the Cal that was at 350 instead of 400 where I like it. I will get a photo when my batteries charge back up.
Any help is appreciated.
Jay
